Amr ibn Al-As reported: The Quraish importer said to him that he heard the Messenger of Allah, peace and blessings be upon him, say, “The Hour will be established and the Romans will be a majority of the people.” Amr said, “Be careful what you say.” The man said, “I have said what I heard from the Messenger of Allah.” Amr said, “If the Prophet said that, indeed, there are four qualities in them: they are the most judicious of people during a tribulation, they are the quickest to recover after a calamity, they are the quickest to return to battle after a retreat, and they behave well with the poor and weak. Their fifth quality is good and beautiful: they are best at preventing the oppression of their kings.”
